Eg. if Form A creates Form B, and Form B then creates Form C, and then I close Form B I would like Form C to also close. So long as Form C has Form B as an owner then it will automatically be freed when Form B is freed.

If I then close form B, form C does not close. Because form B just closing, not freeing.
